Down In The Depths

Swimming does not always have to be about floating in peaceful tranquility. Located in Belgium, Nemo 33 is the world’s deepest indoor swimming pool, consisting of underwater caves, flat platforms at varying depths and a circular pit that descends 33 meters. Kept at a toasty 86 degrees Fahrenheit, it’s the perfect place for anyone taken by the depths of the sea but fearful of the creatures that come along with it.
